I know how to do these, I think I just somehow fudged up the calculations:
1)A pair of narrow slits is illuminated with red light of wavelength [itex]\lambda[/itex] = 633 nm. The slits are separated by 0.10 mm center-to-center. (a) What is the angular separation of the interference maxima near the center of the pattern? (b) How far apart are neighboring maxima if they are observed on a wall 6.55 m away from the slits?
2)Calculate the width of the central maximum in the single-slit diffractiion pattern of yello light of [itex]\lambda[/itex] = 589.0 nm by a slit 0.250 mm wide viewed on a screen 2.00 m away.
Just to give u an idea of how bad I think I screwed up, I got an answer of around 50 m for the second problem.
